I agree with Jeff's logic. But, is there sign of raw gas in the #6 cylinder?
My point is, it is either a SPARK issue or a FUEL issue. One or the other needs to be eliminated so you can concentrate on the missing (FUEL/SPARK) key ingredient.
SPARK: Regardless of what a spark tester indicates, if the plug is WET but the tester says there's current, then the spark energy is bypassing the spark gap,
especially so if the #1 plug looks normal! Start there.
FUEL: IF however, the #6 plug is dry
except perhaps for some oily residue (from the crankcase), coupled with the fact that if the #1 plug (in this case) is "normal", then fuel is the issue:
either the fuel is blocked within the injector, or the injector itself is bad (most often the internal actuator windings are shorting out - especially injectors susceptible the insulation on the internal windings being dissolved by alcohol. This phenomenon is easily detected by measuring the resistance across the injector WHEN IT IS @ OPERATING TEMPERATURE [especially]!
My best guess (assuming the #1 plug looks normal) is a fuel issue which narrows it to a bad injector or an internal blockage perhaps??
